Last time I had issues like this it was root rot, but I checked the roots and they are fine, what should I do? Up cal mag a little more?
0 distilled.Whats your source water ppm?
How much does your ph change in 24 hrs?0 distilled.
I’m not sure, I have it currently at 100% 21” awayHow much does your ph change in 24 hrs?
Start with cal mag and add until you reach 125ppm. Then add grow until you hit 500ppm.
Happen to know the lux value your lighting is at?
Check ph 24 hrs apart at the same time of day then post. With little to no alkalinity you may have issues as the grow goes on.I’m not sure, I have it currently at 100% 21” away
And it might swing .1 or .2 ppm dropped a bit, but I added back calmag and got it back to what the starting ppm was thinking it was deficiency.
I’ll check the lux when I get back home tonight. I do have ph up, I also started using silica, not sure how much to feed(Ppm wise) so I went real light dose.Check ph 24 hrs apart at the same time of day then post. With little to no alkalinity you may have issues as the grow goes on.
Download light meter by my mobile tools dev and post the lux value at the top of the plant. Should be around 20k right now.
Do you happen to have ph up?
Ran the app, it’s reading about 330 Lux? That can’t be right.Check ph 24 hrs apart at the same time of day then post. With little to no alkalinity you may have issues as the grow goes on.

How big is the tent?I run photos all the way through. Current flower under P2500's. The results under these lights is excellent imo.

No cal mag in RO water?Drop the calmag for a while and wait until you see the plants need it, in 3.5 gallons of nuit mix, I only ever put in 2ml per month of calmag, and move your PH up to 6. I personally would use either hydrogaurd or sensizyme, but not both together. Plants look fine colour wise so they're picking up nuits.

Yes, yes, and iPhone 11 Pro..Screen facing up? Light meter app? Maybe an older phone?
